1. Overview
The EzAntennaTracker system, is the first commercially available antenna tracker designed for FPV/UAV
flight.
It operates by sending a digital telemetry stream down one of the audio channels of an A/V link, via the
EzOSD module. This telemetry stream contains information on the plane’s GPS location, and other
information available to the EzOSD.
This telemetry stream then exits from the audio jack of the ground-based receiver, and can be used for
various purposes.
1) It can be simply recorded to the audio/video recorder, and ‘re-played’ through Google Earth™ to
show the path that the model took during the flight/drive/sail. This case requires no additional
hardware.
2) It can be recorded, as above, but used to find a lost plane in the event of a distant crash. The gps
coordinates of the last packet sent should indicate roughly (or best case, exactly) where the plane
crashed. Again, no additional hardware required.
3) It can be fed to an antenna tracker, which is driving a pan/tilt mount. This can aim a directional
antenna at the plane during the entire flight, greatly reducing dropouts (and with the added bonus that
the antenna points to where the plane landed/crashed in the event of a ‘problem’.
This manual is dedicated to the third purpose, the use of the telemetry stream to drive an antenna
tracker.
